随着建筑工业的发展，混凝土的研究和生产正向着高强度、高流态、多功能的方向发展。高强抗渗防裂微膨胀混凝土正在日益受到广泛地应用。笔者仅将明矾石微膨胀混凝土的试验及应用实例简介如下：1明矾石田服刑付出胀的作用机理硅酸盐系列水泥是建筑上的常用水泥，其硅酸盐水泥熟 With the development of the construction industry, the research and production of concrete is developing in the direction of high strength, high flow, and multi-functionality. High-strength impervious and crack-proof micro-expanded concrete is increasingly being widely used. The author only describes the experiments and application examples of alum-clad micro-expanded concrete as follows: (1) The action mechanism of Mingshi Ishida’s serving the expense of sterilizing The silicate series cement is a commonly used cement in construction, and its Portland cement is cooked.
